Controller Area Network (CAN) Fault Tolerance

WARNING: This page is about a different car, the 2012 Ford Escape. However, it is still accessible from the selected car via links, so may be relevant.
NOTE: The oscilloscope traces below are from the Integrated Diagnostic System (IDS) oscilloscope taken using the IDS pre-configured Controller Area Network (CAN) settings. The traces are for both data (+) and data (-) taken simultaneously (2-channel) at a sample rate of 1 mega-sample per second (1MS/s) or greater.

Traces below are viewed at 500mV per division (vertical axis) and 20 microseconds (20μs) per division (horizontal axis). Readings taken with a different oscilloscope vary from those shown. Compare any suspect readings to a known good vehicle.
